Featuring DATEL’s ultra-wide, 18-72V, input voltage range, this new Family of

A-Series, TWR (triple-output) DC/DC converters deliver up to 15 Watts. These

devices each have a primary +5V output that can source from 1 Amp to 1.8 Amps

(model dependent) and auxiliary ±12/15V outputs that can source from ±150 to

±250mA (model dependent). All models can simultaneously source maximum rated

current from both primary and auxiliary outputs. The nominal input voltage for each

model is 48V.

As members of DATEL’s new A-Series, the 12-15W triples exhibit both low cost

and outstanding long-term reliability. Their design combines straightforward circuit

topologies, proven SMT-on-pcb construction methods, the newest components, and

highly repeatable automatic-assembly techniques. The A-Series TWR’s superior

durability is substantiated by a rigorous in-house qualification program that includes

HALT (Highly-Accelerated Life Testing), which is designed to detect any potential

electrical, mechanical or process weakness.

Packaged in standard, 2" x 2" x 0.45", shielded metal cases with non-conductive

coatings, these fully isolated (1000Vdc minimum) DC/DC’s offer excellent line and load

regulation. Additionally, these A-Series triples have non-latching output current

limiting, input overvoltage shutdown, input reverse-polarity protection, and output

overvoltage clamping to protect both the power converters and their loads. All

A-Series TWR models are fully EMI characterized and designed to meet UL1950,

IEC 950, CSA 950 and EN60950.
